ABSTRACT:
The present invention relates to a process for the electrochemical synthesis of alpha-saturated ketones by electrochemical reduction, in an organic solvent medium, of alpha-saturated organic halides in the presence of CO.sub.2 and of a catalyst based on nickel complexed with a bidentate organic ligand containing two nitrogen atoms, such as 2,2'-bipyridine and, optionally, with an ethylenic coligand.
The anode, made of a metal chosen from the group consisting of the reducing metals and their alloys, is consumed during the electrochemical reaction whose site it is. It is preferably made of magnesium.
This process is simple to use and allows a single-compartment cell to be employed.
Alpha-saturated ketones are compounds commonly employed in the chemical industry, particularly as solvents or synthesis intermediates.
